Explicación paso a paso:

Datos:

a) 1/2 × 3/4

= (1×3) / (2×4) = 3/8

=3/8

b) [2/3][1/2]

= (2×1)/(3×2) = (1)/(3) = 1/3

=1/3

c) [4/5][3/2]

= (4×3)/(5×2) = (2×3)/5 = 6/5

=6/5

d) 6/9 × 6/4

= (6×6)/(9×4) = (2×3)/(3×2) = 3/3 = 1

=1

e) 15/8 × 4/5

= (15×4)/(8×5) = (3×1)/(2×1) = 3/2

=3/2

f) 3/7 × 2/3

= (3×2)/(7×3) = (2)/(7) = 2/7

=2/7

g) 3/2 × 1/3 × 4/5

= (3×1×4)/(2×3×5) = (1×2)/(5) = 2/5

=2/5

h) [4/3][5/6][1/4]

= (4×5×1)/(3×6×4) = (5×1)/(3×6) = 5/18

=5/18

i) 1 5/6 × 2 1/7

= {[(1×6)+5]/6} x {[(2×7)+1]/7}

= [(6+5)/6] x [(14+1)/7]

= [11/6] x [15/7]

=(11×15)/(6×7) = 165/42

=165/42

j) 2 1/2 × 1 3/4

= {[(2×2)+1]/2} x {[(1×4)+3]/4}

= [(4+1)/2] x [(4+3)/4]

= [5/2] x [7/4]

= (5×7)/(2×4) = 35/8

=35/8
